Hi, I am new and pleasingly stupid about this, pleasingly because I am a blank slate learning from you all, and I love it. Okay 1st sourdough from APF turned sour in 3 days. This one I will refer to as JOBA, is made from a medium Rye, with a lot of grain in it. I am using the method of unsweetened juice, 2T at a time daily for 3 days. All is fine, have a thin plastic and rubber band lid on it. This morning when I went to feed JOBA, I noticed he has white white fuzz on the edge of the glass. I know I have not started a chia pet, and am wondering if something is wrong can I save JOBA, or must I create another one. this is Day 3, still thick, and had white fuzz.
